From trench safety to lifecycle reliability: A project-control framework for water and sewer reticulation delivery in U.S. communities

Among all civil infrastructure projects, water and sewer reticulation projects have some of the highest capital requirements, technical challenges, and public Importance. Project delivery teams are under tremendous pressure to deliver reliable, code-compliant, and cost-effective systems as the American Society of Civil Engineers (ASCE) continues to grade the state's infrastructure for drinking water and wastewater systems as a D+ over the last two years. The Environmental Protection Agency (EPA) estimates that there is a combined $744 billion funding gap between 2021 and 2040 for drinking water and wastewater infrastructure (ASCE, 2021; EPA, 2023). However, ongoing issues continue at water systems—According to EPA, approximately 240,000 water main breaks happen each year, causing water system emergency repairs and water losses of at least $2.8 billion each year for water systems in the United States (EPA, 2023; Folkman, 2018). This article provides a comprehensive, evidence-based project-control framework that combines utility sequencing, trench control, pipe installation control, quantity measurement methods, inspection readiness checklists, detailed policies around pressure and leak testing, quality assurance/quality control (QA/QC) documentation systems, and project closeout procedures. This framework incorporates federal regulatory guidelines, industry best practices from the American Water Works Association (AWWA), OSHA trench safety regulations, and peer-reviewed research in the field of infrastructure lifecycle management to provide project managers, site engineers, and quality personnel with tangible, usable tools to minimize rework, eliminate safety incidents, and increase the operational service life of reticulation assets.
